Alexicacus

Apollo Alexicacus (Ancient Greek: Ἀλεξίκακος), the "averter of evil", was an epithet given by the Ancient Greeks to several deities, such as Zeus, and Apollo, who was worshiped under this name by the Athenians, because he was believed to have stopped the plague which raged at Athens in the time of the Peloponnesian War. It was also applied to Heracles.
